When Lu Fan woke up from his 137th reincarnation, he found himself involved in a game of genetic experiments and rules that spanned time and space. Carrying the ability of "time and space retrieval", he accidentally activated the ancestral witch gene hidden in his bloodline, and the system AI "Zero" that controlled all this was actually a fragment of the dark side split from the first generation of time and space lord. As the Tianshu Council activates the core of time and space to summon the red flame demon dragon, Lu Fan must join forces with demon hunters, spiritual archers and witch priest Jiuli to start a life-and-death race in the rift between the city and the ancient world.
